You definitely have low testosterone and I'm guessing you are not feeling too good. I know I really wasn't with levels in the mid 300s.
It's also inappropriate IMO for an endo to tell you "you're fine" with testosterone levels in that range. I'd read that as "for liability reasons because of your age I'm going to cover my ass and not treat you by lying to you about the severity of your condition." (Or he's just ignorant but for an endo that's ridiculous - 232 is clinically hypogonadal).
Anyway, have you ever used any hormonal product (AAS, prohormones, sarms, etc?).
My suggestion is to see a men's health/TRT clinic and discuss starting treatment. If you've had low T for >1 year it's probably a persistent problem if your diet/training/lifestyle is reasonable.
Basically if you have chronic low T your main options are TRT, long term clomid (to raise levels), long term HCG. Some people, especially those who have not messed up their HPTA with hormone use are able to increase their T naturally through diet/lifestyle changes and you can find examples of tis online.
In your situation if you haven't used any hormones I would try aggressive OTC T raising strategy and see how it works, and if it doesn't, just start TRT.
I have (likely) AAS induced low T and I was miserable for a long time and am feeling better after starting clomid last month, but I will be switching to TRT as it is likely to be more effective. Personally, I wasted a lot of time trying the OTC test boosters and strategies (higher fat diet, IF, etc.) but you may be different if you haven't used hormones.
